FIG. 1 is a view provided to explain a cooking system, according to anembodiment of the present disclosure.

The cooking system 1000 includes a cook top 100, a range hood 200, and auser terminal device 300.

The cook top 100 is a cooking device configured to generate heat usinggas or electricity, and that has one or more burners to heat food to becooked or cooking containers placed on top of the burners. The cook top100 may be called a gas range or an electric range depending on themethod of generating heat.

Especially, in the case where the cook top 100 is realized as anelectric range configured to generate heat by converting electric energyinto thermal energy, such cook tops may be classified into inductions,hot plates, highlights and the like depending on the heating element.Inductions use the principle where heat is generated by an inductanceaction as a cooking container contacts a magnetic substance, and thusthey are electric ranges that use exclusive containers having magneticproperties. Hot plates use a method of directly heating a metal platehaving heat wires, and highlights use a method where heat wires aredistributed in a circular form to heat a ceramic heater. In other words,highlights use a compromised method of a hot plate and an induction.However, the electric ranges are not limited to the aforementionedmethods.

The range hood 200 is a ventilating device configured to discharge orpurify smoke or smell generated from food being cooked in the cook top100 through an exhaust pipe that connects a main body of the range hood200 and outdoors. The range hood 200 is mostly arranged above the cooktop 10. The range hood 200 inhales the smoke or smell using suctionforce generated by an exhaust fan that is supplied with power source androtates by the received power source, and then exhausts to the outdoorsthe smoke or smell from which foreign matter has been filtered by afilter.

The user terminal device 300 is a device capable of communicating withthe cook top 100, and may be realized as various electronic devices suchas, for example, smart phone, tablet PC, notebook PC, remote control,wearable device and the like.

The cook top 100 and the user terminal device 300 may be connected toeach other via wireless communication and transceive data between eachother. FIG. 1 illustrates that the user terminal device 300 is connectedto the cook top 100 to transceive data, and that the cook top 100 andthe range hood 200 are connected to transceive data, but it is alsopossible to have the user terminal device 300 directly connected to therange hood 200 to transceive data therebetween.

Here, the user terminal device 300 may transmit to the cook top 100 acontrol signal for controlling the cook top 100 or the range hood 200,and the cook top 100 may transmit to the user terminal device 300operating information of the cook top 100 and operating information ofthe range hood 200. Further, the cook top 100 may transmit to the rangehood 200 a signal notifying the operation of the cook top 100, a signalfor controlling the range hood 200 according to a control signalreceived from the user terminal device 300, and operating information ofthe range hood 200 to the cook top 100.

Meanwhile, FIG. 1 illustrates an embodiment where the user terminaldevice 300 is connected to the cook top 100 to transceive data, but itis obvious that the user terminal device 300 may be connected to therange hood 200 to transceive data directly without going through thecook top 100.

FIG. 2 is a block diagram schematically illustrating a configuration ofthe cool top, according to an embodiment of the present disclosure.

Referring to FIG. 2 , the cook top 100 includes an inputter 110, acooker 120, a communicator 130 and a processor 140.

Further, the first communicator 131may receive unique address, device name and other information of therange hood 200. By providing and receiving connection information insuch a way, the cook top 100 and the range hood 200 may be paired toeach other. When a connection is established, the cook top 100 maytransmit to the range hood 200 a signal for controlling an operatingstate of the range hood 200 to correspond to an operating state of thecooker 120, and may receive from the range hood 200 state information ofthe range hood 200.

The second communicator 132 may be wirelessly connected with the userterminal device 300 in a Wi-Fi method. Specifically, the secondcommunicator 132 may be wirelessly connected with the user terminaldevice 300 through an Access Point (AP), or directly connected with theuser terminal device 300 through a Wi-Fi direct method. When aconnection is established, the cook top 100 may transmit stateinformation of the cook top 100 to the user terminal device 300, andreceive a control command for controlling operations of the cook top 100from the user terminal device 300. Further, the cook top 100 may convertthe state information of the range hood 200 received through the firstcommunicator 313 into state information having a Wi-Fi form, andtransmit the converted state information having the the Wi-Fi form tothe user terminal device 300 through the second communicator 132.Further, the cook top 100 may convert the control signal for controllingthe range hood 200 received through the second communicator 132 into acontrol signal having a Bluetooth form and transmit the same to therange hood 200 through the first communicator 131.

In another example, the communicator 130 may first transceive variousconnection information such as SSID and session keys to and from therange hood 200 and the user terminal device 300 through an NFCcommunication method, and then use this information to be connected forcommunication and then transceive various signals through a Bluetoothmethod or a Wi-Fi method.

The processor 140 is a configuration for controlling the overalloperations of the cook top 106. Especially, the processor 140 maycontrol the operating state of the cooker 120 according to a usermanipulation input through the inputter 110, and transmit to the rangehood 200 a signal for controlling the operating state of the range hood200 to correspond to the operating state of the cooker 120.

Specifically, the processor 140 may determine whether or not the cooker120 is operating, and if it is determined that the cooker 120 isoperating, transmit a signal for operating the range hood 200 to therange hood 200, and if it is determined that the cooker 120 is stoppedfrom operating, the processor 140 may transmit a signal for stopping therange hood 200 from operating to the range hood 200. Here, operation ofthe range hood 200 may mean operation of the exhaust fan 210 provided inthe range hood 200.
